Justin har fått husarest, fake or not?

Justin Bieber might have a bazillion dollars in pocket money at his disposal, but his mom Pattie wants to make sure he doesn?t end up blowing it all, reports ninemsn.co.au

Pattie Mallette has cracked down on his excessive spending after he dropped a whopping $160,000 on a custom made Range Rover from the ?Project Kahn? in early November.

?Pattie blew a gasket when she learned about Justin?s wild spending spree, as a result, she is forbidding him from driving until he turns 18, unless he?s accompanied by an adult chaperon.? a source told National Enquirer.

Justin Bieber already owns a custom Cadillac ?Batmobile? and a Ferrari, probably that?s why Pattie thought a customised ?Project Kahn? Range Rover ? complete with a souped-up Cosworth engine, custom paint job and a sound system worth tens of thousands of dollars ? was a bit over the top.

?Pattie is trying to get Justin?s wild spending under control,? added the source.
